Abstract
Objetive: Describe the histological and immunohistochemical features of nine genital tract adenomatoid tumors . Material and methods: Nine cases of adenomatoid tumors were collected from the files of the Pathology department at a private hospital (ABC Hospital). Tumors were studied from a histological and inmunohistochemical perspective. Results: Eight women and one man were studied. Age range was 28–54 yrs. Tumors were located in the uterus (seven), fallopian tube (one) and epididymis (one). Tumor size ranged from 0.4 to 5.8 cm. We observed three histological patterns: adenoid, angiomatoid and solid. Arrangement of the neoplastic tubules around fascicles of smooth muscle; angiomatoid pattern with a peripheral location, and solid and adenoid patterns with a central location in the tumor were some of the observed histological features. Immunohistochemically all tumors exhibited strong and diffuse positivity for calretinin and AE1/AE3. Thrombomodulin was positive in all tumors (focal and weak in angiomatoid pattern and diffuse and strong in adenoid and solid patterns). The CK5/6 antibody was positive in seven tumors (diffuse in three and focal in four). Two tumors were negative for this marker. All tumors were negative for CD31.©Gaceta Médica de México
